VRWorks is Nvidia's software development kit (SDK) targeted at VR application developers and headset makers. According to Nvidia, this move should allow Unity developers to easily leverage VRWorks-specific features like Multi-res Shading and VR SLI.

Multi-res Shading purports to improve VR rendering performance by rendering different parts of the VR view port at the appropriate levels of fidelity needed to provide a convincing experience, potentially resulting in more efficient use of rendering resources. VR SLI, on the other hand, allows developers to assign a graphics card to handle rendering for each eye, delivering performance scaling for multi-GPU systems.

Unity support looks like a boon for the green team's VR efforts. According to Unity Technologies, 45% of the "full feature game engine market" uses Unity, and its website counts 4.5 million registered developers. The fact that Unity offers cross-platform support across all major desktop and mobile OSes likely didn't escape Nvidia's attention, too.
